Replacing the Fan for the Quantum Ultra
®
Power Supplies
The largest (top) fan cools the power supplies. If this fan fails, you can order a new fan from
www.extron.com and replace it as described in this guide. The fan is hot-swappable, that is, it
can be replaced while the Quantum Ultra is operating, without the need to power down the unit.
ATTENTION:
• When a fan fails, replace it immediately. Do not run the unit for a long period without
a fan.
• Lorsqu’un ventilateur cesse de fonctionner, remplacez-le immédiatement. NE
prolongez PAS le fonctionnement de l’unité sans ventilateur.
1. Use a tool to loosen the two thumbscrews on the cover panel and remove the panel (see
gure 1 at right). The thumbscrews cannot be removed completely.
2. Use a tool to loosen the thumbscrew that holds the fan to the chassis (see gure 2,
1
).
ATTENTION:
• Thumbscrews should be tightened with a tool after both initial installation and
subsequent access to the panel.
• Les vis doivent être serrées avec un outil adapté après la première installation et
l’accès postérieur au panneau.
